4-6 Compaq Parallel Database Cluster Model PDC/O1000 for Oracle8i and Windows 2000 Administrator Guide Planning Cluster Interconnect and Client LAN Components PDC/O1000 clusters running Oracle8i Parallel Server can use a redundant or non-redundant Ethernet cluster interconnect. A redundant cluster interconnect is recommended because it provides fault tolerance along the entire cluster interconnect path. Planning an Ethernet Cluster Interconnect NOTE: Refer to the technical white paper Supported Ethernet Interconnects for Compaq Parallel Database Clusters Using Oracle Parallel Server for detailed information about configuring redundant Ethernet cluster interconnects. This document is available at www.compaq.com/support/techpubs/whitepapers Before you install an Ethernet cluster interconnect in a PDC/O1000 cluster, review these planning considerations: I Whether to use a redundant or non-redundant Ethernet cluster interconnect. A redundant Ethernet cluster interconnect is recommended because it provides fault tolerance across the cluster interconnect. I Whether to use two Ethernet switches or two Ethernet hubs for the cluster interconnect. If your cluster will contain or grow to three or more nodes, you must use two Ethernet switches. I Whether to use two dual-port Ethernet adapters in each node that will connect to both the cluster interconnect and the client LAN or to use separate single-port adapters for the Ethernet cluster interconnect and the client LAN.
